Kroll Ontrack Retrieving Data from Overwritten LTO-6 Tape Cartridges

In response to service provider

Kroll Ontrack, Inc. announced a technical breakthrough with the development of a toolset to retrieve overwritten data from LTO-6 tape cartridges.

Overwritten LTO-6 tapes cause major problems for organizations utilizing them as part of their backup protocols, as the original data on the tape is no longer available and crucial information can be permanently lost.

Kroll Ontrack investigated the challenge of retrieving data from LTO-6 tapes in response to a service provider that had accidentally overwritten data on a client’s backup tape cartridge. The company had already developed software and hardware tools to recover data from earlier tape designs (from LTO-1 – LTO-5). However, with LTO-6, originally released in November 2012, some significant changes were made in the design that were incompatible with Kroll Ontrack’s existing LTO tape recovery tools.

The adoption of LTO-6 tapes is accelerating and we are seeing an increasing stream of tapes that have been overwritten, either through administrative or software errors,” explained Todd Johnson, VP of data recovery operations, Kroll Ontrack. “The challenge with all tape media is that once a new block of data is written at the beginning of a tape that is full, all of the data stored on that tape after the new block becomes inaccessible. So if a tape is accidentally initialized or is even partially overwritten, historically it was not possible to recover the old data.

In an effort to maximize storage and manufacture faster and more efficient tape design, the specifications of LTO-6 changed fairly from previous versions,” said Jeff Pederson, senior engineering manager, Kroll Ontrack. “In response, our engineers made the necessary changes to make our recovery solution compatible with LTO-6, allowing us to restore data even when it has been accidentally deleted. This recovery capability is available to service providers and organizations from our recovery labs across the world. As far as we are aware, we are the only data recovery company to provide this service for LTO-6 tapes.

LTO-6 tape services are available as part of Kroll Ontrack’s standard data recovery portfolio. Customers have access to firm’s data recovery lab and ISO-5/Class 100 clean-room environment, as well as service and support.
